GRAIN CLEANER.

Application filed September 10, 1919. Serial No. 322,796.

To all whom it may concern."

Be it known that I, Ronnn'r H. OWEN, a citizen of the United States, residin at Buttefln the county of Silver- Bow and State of Montana, have invented new and useful Improvements in Grain Cleaners, of which in the detailed description to follow.

The invention is illustrated by way of example in the accompanying drawings, in which:

Figure l'is a longitudinal sectional View Figure 2 is a transverse sectional view taken substantially on the lines of Figure 1.

Figure 3 is a top plan view of the re ceptacle or housing.

Figure 4 is a perspective view ofa slide or valve employed in connection with the receptacle or housing.

-Referring to -the drawings more particu larly, in Figure 1, 60 indicates generally a fan housing or easing into which grain may be delivered. Within this housing there is positioned a shaft 59 supporting the fan blades 61, and this fan may be employed for forcing grainthrough a conduit 64 which communicates through the opening 63 with a receptacle 62. The receptacle 62 is preferably of the shape shown, and with in the receptacle there is arranged a pair 15 of division walls 62 and 63. The division wall 62 at its upper end engages with the upper end portion of the division wall 63', while its lower end is provided with an offset portion 61 which is adapted to form a restricted passage 67 through which the grain deposited in the receptacle through the conduit .64 will pass. The division wall 63 is adapted to establish a separate passage 6l which communicates at its upper end with the upper end portion of the rethrough the transverse passage 66. It is apor plate 69.

'ceptacle 62 and its lower end substantially inalignment with a transverse passage 66 provided in the one side of a discharge chute 65.

The upper end wall of the receptacle 62 is provided with a plurality of openings 68 and over which. there is positioned a plate member 69. The plate member 69 is slidably held by the means of pair of angle members 70 and is adapted to be moved with relation to the opening 68 to regulate the passage of air under atmospheric pressure into the receptacle 62.

I The present cleaning arrangement may be incorporated with a thrashingmachine or 70 with other suitable means whereby gram may "be delivered into the receptacle 62.

The grain may be delivered to this receptacle with foreign particles therein. The grain will gravitate through the opening 67 and from thence pass into the chute 65. The air pressure used for delivering the grain into the receptacle 62 will pass through the passage 64 and from thence 8O parent therefore as the grain leaves the receptacle 62 and passes into the chute 65- it will be subjected to a transverse current of air from the passage 64. and thereby clean the same of foreignparticles which may be '85 removed by a blast of'air.

v The strength of the current of air passing transversely of the grain may be regulated through manipulation of the valve member Having thus described my invention, I claim 1. In a device of the character described, a grain cleaner comprising a receptacle communicating at its lower end with a discharge passage, and also having communicating therewith a conduit through which grain may be discharged into said receptacle under air'pressure, a division wall within the receptacle adapted to form a re stricted passage through which the grain entering the receptacle must pass before proceeding into the discharge passage, and a second division wall within the receptacle adapted to form a channel whereby to cause the air entering with the grain to be di-. rected against the grain after passing through said restricted passage in the receptacle.

2. In a device of the character described,

a grain cieaucr comprising a receptacle communicating at its lower end. with a discharge passage, and also having communicating therewith a conduit through which grain may he discharged into said receptacle under air pressure, a division wall within the receptacl adapted to "form a restrict d passage through which the grain entering the receptacle must pass before proceeding into the discharge passage, a second division wall within the receptacle adapted to form a channel whereby to cause the air entering with grain to be directed against the grain after passing through said restricted "go in the receptacle, and a valve regd vent in the top of the receptacle whereby to regulate thevelocity of the air directed against said grain.

device of the character described, a grain cleaner comprising a receptacle communicating at its lower end with a discharge passage, adivision wall within the receptacle adapted to form acompartment into which grain may be discharged under air pressure and also adapted to form a restricted passage or outlet at the lower end of said compartment through which the grain discharged in said compartment may pass, and means whereby the air under pressure resulting from the delivery of the grain to said compartments may be delivered to transversely pass through the grain after the grain has passed through said rest 'icted passage.

4. In device of the character described, a grain cleaner comprising a receptacle coinniunicating at its lower end with a discharge passage, a division wall within the receptacle adapted to form a compartment in which grain may be discharged under air pressure and also adapted to form a restricted passage or outlet at the lower end of said compartment through which the grain discharged in said compartment may pass,

means whereby the air pressure resulting from the delivery of the grain to said compartments may be delivered to transversely pass through the grain after passing through said restricted passage, and controlling means and an outlet in the receptacle adapted to establish communication with the compartn'ient to which. the grain is delivered and the atmosphere.

53. in combination, receptacle having a division wall therein adapted to form a com partment, said compartment having an outlet through which grain to be separated may be delivered, a grain delivery conduit co1nmunicatingwith said opening, means whereby air pressure may be introduced into said conduit for blowing grain into said com- -part1nent of the receptacle, said compartment having a restricted outlet at the lower end thereof through which the grain may pass, and means whereby the air discharged in the compartment when delivering the grain thereto may be utilized for subjecting the grain to a transverse current of air to clean the same after its passage through said restricted openin 6. it separator, comprising a receptacle having a discharge opening, means whereby grain may be delivered to said receptacle under air pressure, and means whereby the air pressure for delivering said grain may be utilized for subjecting the delivered to a cleaning process.

7. A grain separator, comprising a receptacle having a discharge opening, whereby grain may be delivered to said rcceptacle under air pressure and means whereby the air pressure for delivering the said grain to the receptacle may be utilized for subjecting the grain discharged there from to atransverse current of air for cleanin said grain.
